Abstract
A two-part, thermally curable epoxy composition comprising an epoxy resin; a curing agent prepared from a substituted pentafluoroantimonic acid and a substituted benzene having an amino substituent and an electron-withdrawing substituent on the benzene ring; a polyol; and a toughening agent. The compositions exhibit desirable green strength and pot life.
